It is indicated that retained austenite in microstructure can inhibit the initiation and propagation of fatigue crack, improve the resistance to impact fatigue and decrease impact fatigue wear.
试验得出，残余奥氏体可阻止疲劳裂纹的萌生和扩展，提高冲击疲劳抗力，降低冲击疲劳磨损。
Size of reinforcement bar significantly affected the fatigue life of materials, the larger the matrix space can make more resistance to crack propagation.
增强柱的尺寸对材料疲劳寿命影响较大，较大的基体空间可以为裂纹扩展增加更多的阻力。
